Smartphones and tablets can be great creative canvases for brand advertisers, and many agencies are helping brands go big on mobile. But it’s hard for agencies and advertisers to experience the full interactivity of mobile rich media -- mobile video and HTML5 ads -- through static images alone. Last night at our annual Creative Sandbox event in New York, we unveiled the new Mobile Ads Showcase App, which lets you experience mobile ads exactly as your users will.

The app lets you explore what best-in-class advertisers are doing with mobile rich media, and learn about all that’s possible with Google Mobile Ads. Additionally, agencies can use the app as their mobile portfolio by coding, testing and uploading their HTML5 ad examples to the MRAID-compliant “My Ads” screen. The app is now available for Android smartphones and tablets through the Google Play Store.
